Abstract (en)
The configuration of an eyeglass frame is measured with an eyeglass frame configuration measuring device and entered into a lens configuration measuring device which, on the basis of the input configurational data, measures the edge positions of a processed lens. Any insufficiency in the diameter of the lens to be processed relative to the frame configurational data is detected by a grinding machine which measures the lens configuration excluding the undersized area, which is displayed in a display section with respect to the desired frame configuration. The operator makes a decision as to whether he should process the lens and enters a command for processing if he finds it necessary. In response to the entry of the command for processing, the grinding machine computes the data for processing the lens on the basis of the lens edge positions, interpolates the data for processing the undersized areas on the basis of the edge positions as measured with the lens configuration measuring device, and performs lens processing with the carriage and lens grinding sections being controlled on the basis of the measured data. <IMAGE>
